Abstract
An antenna for a transceiver which does not require a transmit/receive switch, typically a cordless telephone, is formed by a printed circuit board (10) which is subdivided by two separating slits, located in respective separating planes (A, B) into three adjacent regions, defining a first end region (F2) adjacent a first slit, a second end region (F3) adjacent a second slit, and an intermediate or central region (F1) between the slits. Electrical surfaces or conductive tracks are connected across the slits (18, 19) by high-frequency impedance elements, such as high-resistance resistors or chokes, (20, 21). A high-frequency unit is located preferably beneath the intermediate region, and has a transmitter output stage, connected to a first lateral region (F2) forming an antenna, with the intermediate and other end region (F1,F3) forming director and reflector elements; a receiver input of the high-frequency module is connected to the other end region which, then, will form a receiving antenna with the intermediate and first end region forming, respectively, director and reflector elements. The high-frequency connections to the respective antennae are located close to the separating slits.
